Application filed September 14, 1 925. S eriaLNo. 56,356.

' h/Iy invention is a holder for that form of shutter release known asthe antinous release or cable release or push-cord release.

" ,I-n the drawing t'orming a part of this application, Figure 1 is afront view of the holder, Figure 2 1s a side view, Figure 31s anendlviewas seen from below when the 'length of the bottoniofthe Us. The twoholder is in the usual position; Figure 4 is a front view of part ofcamera front show ing the holder in position on the front and alsoshowing the relation of the holder to the release and the shutter;Figure 5 shows one of the two blanks that are used in mak ing theholder.

The holder is made of three pieces of material, two pieces of springsheet metal or other elastic material and a small machine screw. Thetwopieces of sheet metal are alike in all respects. The form of one ofthese is shown in Figure 5. It has a body portion 0 from which extendstwo pairs of fingers '1, 1, and 2, 2. These fingers are formed by slots3 and 4 cut in the metal.

In making the holder these sheet metal blanks are bent, each one at twoplaces shown by the dotted lines in Figure 5. After bending, each piecewhen seen edge-on takes the approximate form of a capital U, flat on thebottom with one angle a little more than a right angle, the other anglea little less;

This is seen best in Figure 2. The upright parts of these capital We arereferred to as the arms when taken entire, but the separate parts formedby slotting the arms are called the fingers. The lower part of thecapital U is called the'bottom. Two of these U form pieces are placed.with their open ends facing each other and then the two are telescoped'the first, as seen in Figure 2. These overlapping short fingers 1 formthe yoke which holds the two parts of the release together, and by whichthe release is attached to the camera front, as explained later. Indoing this thetwo long slots 4, 4 register, as do the short slots 3, 3.Then the screw 5 is inserted in the two short slots to clamp the twopieces together. This screw at the same time serves to clamp the holderto the camera front. This is best shown in Figure 2. This figure showsin dotted lines the handle end of the release held in the holder.

The -completed holder has roughlythe term of a box, with'open sides,Figure 2.

The form and structure ofthisbox are evident ,from the way in which itis made. A

slot extends the entire length of its topand continues -abo-uttwo thirdsthe way down through 115$ ends, that 1s two thirds of the ends justmentioned are not quite parallel as the box is a little longer at thetop than lower down. In other words, the ends are divergent towards thetop of the holder. This shape helps hold the release handle.

The above-mentioned slot 4 is formed by the overlapping andregisteringof the slots 4 of the two blanks. fingers overlap at the sametime. fingers thus close the top or" the box.

The holder is adjustable in size to fit large 7 or small releases. Thisadjustment is carried out by telescoping the two U-pieces more or less,as may be necessary, and clampingthem by the screw 5. This adjustmentshould be such that a moderate pressure is required to insert therelease handle, after which the ends of the box spring apart slightlyand grip the handle.

It is readily seen that the holder prevents the button of the release 6from approachinghandle proper 7 of the release, that is the rollerprevents the release from tripping the shutter. In other words, theholder acts as a lock to the release.

The overlapping long fingers that close the top of the holder (exceptthe slot) prevent either the button or the handle of the release fromentering the top of the box, thus aiding materially in placing therelease in the holder.

This release holder possesses three improvements over my former holder,as shown in U. S. Letters Patent No. 1,548,481 of August 4, 1925. Theseare:

1. The closed top. 2.,Adjustability to fit any size of release. 3.Improved gripping power of the nonparallel flaring ends.

The terms long slot and short slot as used here do not necessarilyindicate the relative length of the slots, but are terms Naturally, thelong' These used to distinguish those slots that extend bers having ashort slot in one arm and a long slot in the other arm, the said longslots extending part way across the bottoms of said U-members, the openends of said memhers telescoping into each other so that the long andshort slots of one member register respectively with the long and shortslots of the other members, and a clamp screw passing through the twoshort slots.

2. A shutter release holder consisting of two U-shaped members, each ofsaid mem bers having a short slot in one arm and a long slot in theother arm, the said long slotsextending part way across the bottoms ofsaid members, the open ends of said members telescoping into each otherso that the long and short slots of one member register respectivelywith the long and short slots of the other member, the bottoms of saidmembers being slightly divergent towards the top of the holder, and aclamp screw passing through the two short slots.

3. A shutter release holder consisting of two U-shaped members, each ofsaid members having a long slot in one arm and a short slot in the otherarm, the said long I slots extending. part way across the bottom of saidmembers, the open ends of said members telescoping into each other sothat the long and short slots of one member register respectively withthe long and short slots of the other member, and a clamp screw passingthrough the two short slots.
